Basic printer troubleshooting: If the power lamp is on but the printer will not print, what quick check should you perform first to resolve the problem?

Introduction / Context:
Printers often appear powered yet refuse to print due to simple state or connection issues. A methodical approach starting with non-invasive checks saves time and avoids unnecessary parts replacement.

Given Data / Assumptions:

• The printer’s power lamp is illuminated.
• No print jobs are emerging.
• We want the quickest, most likely fix before deeper diagnostics.

Concept / Approach:

Most printers have an Online/Ready status. If the device is in Offline or Pause state, the spooler will hold jobs. Verifying the printer is online (via panel button, menu, or software queue) is a fast, safe step that often resolves the symptom, especially after maintenance or button presses that toggled the state.

Step-by-Step Solution:

Verification / Alternative check:

Attempt a self-test from the printer’s panel; if it prints, the device is functional and the issue may be host, driver, or queue related. If Online status resolves the issue, subsequent jobs should flow.

Why Other Options Are Wrong:

• Replace AC fuse: device already powers on; not the first step.
• Power cycle: sometimes helpful but should follow simple state checks.
• Replace ribbon/toner: consumables do not usually block printing unless reported empty; the job would still start with faded output.
• None of the above: incorrect because setting Online is commonly the fix.

Common Pitfalls:

Overlooking a paused queue, selecting the wrong printer, or ignoring panel error icons. Always verify Online/Ready first.

Final Answer:

Make sure the printer is online (Ready/Online state)
